On my site whenever I go to the home page, click on a T-shirt, then the log in button it changes to https which is fine, but as soon as I am ready to add that same T-shirt to my cart i get this security message :
(Although this page is encrypted, the information you have entered is to be sent over an unencrypted connection and could easily be read by a third party.)

How do I stop getting this message?

Here are my setting in http/includes/configure:

/ Define the webserver and path parameters
// HTTP_SERVER is your Main webserver: eg-http://www.kingdomfashionz.net
// HTTPS_SERVER is your Secure webserver: eg-https://www.kingdomfashionz.net
define('HTTP_SERVER', 'http://kingdomfashionz.net');
define('HTTPS_SERVER', 'https://kingdomfashionz.net');

// Use secure webserver for checkout procedure?
define('ENABLE_SSL', 'true');

// NOTE: be sure to leave the trailing '/' at the end of these lines if you make changes!
// * DIR_WS_* = Webserver directories (virtual/URL)
// these paths are relative to top of your webspace ... (ie: under the public_html or httpdocs folder)
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_CATALOG', '/');

Thanks!!!!
